The Prisoner By B.a. Paris Guide

Amelie, orphaned and struggling to survive in London, accepts a "faux marriage" proposal from her wealthy billionaire boss, Ned Hawthorne. The arrangement seems mutually beneficial: he satisfies his family's expectations, and she receives $100,000 to secure her future. However, the dream quickly dissolves when Amelie wakes up in a pitch-black room, having been kidnapped along with her husband. As she languishes in captivity, she begins to realize that her husband's secrets are far more terrifying than her captors' intentions, eventually feeling safer in her prison than she did in her own home.
